Design and Realization of Program for Power System Electromechanical Transient and Electromagnetic Transient Hybrid Simulation

In power system hybrid simulation, the mutual influence between the electromechanical transient process and electromagnetic transient process can be synthetically considered. The routine system can be simulated in the electromechanical mode while the other local network or special component in the electromagnetic mode and it provides a new solution to the study of transient stability and dynamic characteristic of the large-scale power system. Based on the self-developed electromechanical and electromagnetic transient simulation programs and the specific interface algorithm, the platform for power system hybrid simulation is designed and implemented, in which a new data exchange sequence method and correlative data communication and synchronization algorithm are also put forward. As its source code is transparent, controllable and expandable, the flexibility and efficiency are improved. The simulation results show the feasibility of the scheme and correctness of the interface algorithm.
